Today, we can flash some BIOS from an operating system. Is this not quite dangerous, nutrient for viruses? When the OS is active, too many processes are active during this critical step and has a good chance something can go awry. I try to update always from the external usb floppy drive or from an usb stick.

View 4 Replies View RelatedI was trying to recover/reinstall win 7 and bring back my asus laptop to its manufacture state. When I run the recovery media (recovery dvd) that comes with my asus laptop and after answering the prompts, it gives off "missing operating system" message on an entirely black screen. I tried to go to the bios setting by hitting delete key upon boot-up but it does not respond. I switched off and back on several times trying the delete key every time but to no avail. It's an ASUS N61J Series with intel i7.

I'm trying to run a chkdsk form a win 7 64 bit disk and telling it to run on H; (system drive) but it says 'cannot open volume for direct access'.

Is it possible to put 2 Live OS / operating systems on a flash drive? Possibly by making it have more then one partition, but how would the booting work? Anyone have any idea how to do this? Also, how different is a flash drive from an ext. hdd? Can I install Live OSen on a ext. hdd?

View 7 Replies View RelatedNeed a little advice. Still dealing with the nasty infection. I have done a clean install where i wiped my hard drive for about 4 hours.
I am still dealing with the infection when i place a blank disk in the drive it will type into the start menu. I am a little unsure if it would be suitable to reinstall again and flash my bios or get hackthis logs done.
If i should flash my bios how do i do this?
I flashed my BIOS to try and fix a problem I was having with my computer not POSTing after a cold boot. Ever since, my secondary hard drive will start to spin-up and spin-down repeatedly, once Windows loads. It doesn't do that during POST, or if I'm in the BIOS, or anything; just when Windows is running, which makes me think it's a software, rather than a hardware problem.
I'd installed Windows in AHCI mode, and it had always worked, but now, the above problem goes away if I set my SATA controller to IDE rather than AHCI, in the BIOS.
So I think it might have something to do with Windows not being entirely happy with AHCI after the BIOS update.

View 1 Replies View RelatedSuddenly my Win 7 Home Premium x64 will not boot. The system starts, POSTs then loads the DVD driver, then the screen goes black (not blank but "lit up" black if that makes sense). Then nothing. If I use Hiren's boot cd I can boot up using the "boot from HDD" option fine and Windows operates normally. System restore to a previous configuration made no difference to the original problem. I cannot boot into Safe Mode. F8 just offers me boot order options.
- Running the Windows 7 DVD I find: "No operating system is listed on the Repair Windows option."
- Running Startup Repair finds the following error: "the partition table does not have a valid system partition" which it claims to have repaired, but the error remains and Windows will still not boot.
I followed this advice:
Boot 7 dvd to system recovery options command prompt. Type: Diskpart
list vol (find the vol letter e.g C or partition number e.g. 1 for the system partition )
Sel vol C ( or sel vol 1, obviously use the correct letter or number)
act exi
My system partition was easily identified and listed as healthy so I selected it and made it active. The problem still remains exactly the same. My system is self built just over a year ago, to my knowledge has been running fine, without any hardware issues. I'm prepared to do a clean install if that's what it takes but if there is a way to fix the partition problem without that I'd like to explore it first.
"Missing operating system" massage is coming when i start my system and i am not able to start. I think because , i had given "mark partition as active" option for one hard dive (E) in disk management when last time i opened. it did not have any data. i did not know, this will make any problem. Now i am not able to boot windows re installation dvd also. i can only take BIOS settings.

View 5 Replies View RelatedI am trying to update the BIOS of my 'ASrock Z68 Extreme4 Gen3' from v1.00 to v1.20. I am running Windows 7 64bit Ultimate. I got the BIOS file from: [URL]. It did not register the BIOS file I had put on my USB drive when going to my BIOS settings. There is an "Instant Flash" function in there. I have tried to make a bootable USB-drive to do it directly from DOS, but my drive can't be formatted as an MS-DOS boot drive. I have tried using HP DriveKey which seemed to work as intended, but it didn't work, the drive was still not recognized in bios. Do you think it's my drive? I don't have another drive with me right now to try it out. I know this is a not really a Windows 7 issue, but I couldn't find a proper category.

View 1 Replies View RelatedMy laptop is a HP Pavilion dv6500 (dv6647cl) just crashed randomly during basic internet browsing. I turned it back on and I get the Operating System Not Found error. In the BIOS I do not see the hard drive recognized. I connected the hard drive to a different computer and it is recognized and it appears as though nothing is wrong with the drive. Is it safe to say that internally the SATA controller is dead? Will edit after running diagnostics and sector tests on the drive.
View 5 Replies View RelatedMy rather new Sony Vaio started having BSOD crashes, usually (but not always) after being asleep. After the BSOD, the restart would fail, with a message saying the operating system could not be found. But, after a couple restarts or a cold reboot, it would find it and start without problem. I reset the bios to defaults, did a system restore to before the crashes started- no luck. To make matters more complicated, the BSOD flash so quickly I don't get error codes, and no matter what I do (check pagefile size/location, system settings), my computer doesn't make a dump file. The event viewer only lists a critical error that the system rebooted without cleanly shutting down first. I called Sony, they had me run one of their hard drive check programs (not chkdsk and it passed), and then made me reformat/recover using the hidden partition and their recovery software. Besides the annoyance of the clean reformat and all my software settings etc not restoring quite right, three days after the reformat and I have another BSOD, and again, no .dmp file or any other clues (and of course, all the previous error reports got wiped).
